Live unit test
The actual test :
- connect to the relayd on localhost
- list the sessions (should find only one)
- attach to the first session
- receive all the streams
- get all the metadata
- get one index per stream
- get one data packet
Then the session is stopped, destroyed and the daemons killed.
Two tests are also added just to for the lttng commands with a --live

Fix: application SIGBUS when starting in parallel with sessiond
There is a race between application startup and sessiond startup, where there
is an intermediate state where applications can SIGBUS if they see a zero-sized
shm, if the shm has been created, but not ftruncated yet.
On the sessiond side, we need to ensure that the shared memory is writeable by
applications as long as its size is 0, which allow applications to perform
ftruncate and extend its size.
On the UST side, another commit needs to ensure that UST can read the shared
memory file descriptor with a read() system call before they try accessing it
through a memory map (which triggers the SIGBUS if the access goes beyond the
file size)

After sending each data packet in live, we need to check if new metadata

Since the data and the metadata are handled by two different threads,

the data thread flushes the metadata stream and waits on a conditionnal
variable. When the metadata thread finishes to send its data, it wakes
up the data thread which can send its index.

To write an index on disk, we need to know all the fields sent by the

Since the control and data connection are not synchronized, this process
happens in two separate steps synchronized by an HT indexed by the
index_handle and the net_seq_num.

Enable support for installcheck.
Enable execution of tests via `make installcheck`, i.e. against a fully
installed
LTTng.
The patch simply adds the same rule to the installcheck target that is
used for check. Testing with an OpenEmbedded build shows the unit_tests
suite to work fine, while the fast_regression suite contains many
failures not present when run as `make check`.

Fix: remove periodical flush test from make check
This test is racy for the following reasons. It expects that the
subbuffer flush timer always produce a coherent trace after a period of
time but this cannot be guaranteed without the upcoming live feature.
A test based on time expectation is a bit flacky so disable it for now
until we have live tracing.

Fix: consumer data pending for empty streams
We should at least output one packet before a stream can be considered
as readable. So far, for PID buffers, if an application exits at the
wrong timing before a stop waiting for data pending, empty streams could
be visible by a babeltrace executed after data pending incorrectly
returned false.
Fix it by considering a stream for which the consumerd has written 0
bytes to the output as having data pending.
This applies to 2.3-rc and stable-2.2.

Fix: hash table growth (for small tables) should be limited (v2)
Buckets with many entries encountered in a hash table could cause it to
grow to a large size, beyond the scope for which this mechanism is
expected to play a role when node accounting is available. Indeed, when
the hash table grows to larger size, split-counter node accounting is
expected to deal with resize/shrink rather than relying on an heuristic
based on the largest bucket size.
This is fixing an issue where we see hash tables sometimes reaching 65k
entries index (65536*8 = 524288 bytes) for a workload limited to adding
1000 entries and then removing all of them, done in a loop (random
keys).
